A Testers Guide to the Illusions of Unit Testing

One area that testers might be able to enhance their contributions to software development teams is how we perceive and contribute to unit testing. Being able to influence this type of testing in a positive manner is a skill that testers will need to get to grips with, as more companies start to embrace a model of lone testers in cross functional teams. The shift of focus from primarily the testing that testers do, to the testing that the team does, is a key shift in thinking and behaviour.

To facilitate this shift, I believe testers busting their own illusions about this aspect of building something good would bring us much closer to developers and help us realise what other layers of testing can cover most effectively. The last point is pertinent here, as knowing and guiding unit testing brings the role of integration, acceptance and exploratory testing into sharp focus.

This is a topic that has always intrigued me, having predominantly worked as a single tester on a team for the last five or so years. I reached out to the community with the question “What do testers believe about unit testing?” and received a lot of engagement. The good users of Twitter added another 50 or so illusions that testers might have about this layer of testing. I figured that based on that level of engagement, maybe this would make an interesting talk! It wasn’t only testers who responded too, suggesting that there might be some shared illusions about unit testing that are cross disciplinary.

The growing list delighted me, so I wrote a blog with the raw list, it can be found here http://testingisbelieving.blogspot.co.uk/2017/12/testers-guide-to-myths-of-unit-testing.html

The list alone is interesting but now I would like to share my analysis of it with you, focusing on:
  • Recurring themes within the list and how to address them as a tester or developer.
  • Particular illusions to look out for with examples from my recent past.
  • A guide for developers to engage with testers on unit testing, and testers with developers.
